HYPERSENSITIVE TO RED AND BLUE 1, a ZZ-type zinc finger protein, regulates phytochrome B-mediated red and cryptochrome-mediated blue light responses.

The Plant cell - 1 Mar 2005

Kang Xiaojun, Chong Jason, Ni Min

Abstract excerpt

Plant photoreceptors that regulate photomorphogenic development include red/far-red-light-absorbing phytochromes and blue/UV-A-light-absorbing cryptochromes. We have undertaken a genetic screen to identify additional components downstream of the photoreceptors in Arabidopsis thaliana. We identified a short hypocotyl mutant under red and blue light, hypersensitive to red and blue 1 (hrb1). Mutation in HRB1 also...
